compositions N: x=3.5% powder 2
The method preparing following compositions is that (1) merges and heating aqueous phase A to 75 DEG C, (2) merging and heating fat phase B to 75 DEG C, (3) fatty phase B is slowly added in phase A to form emulsion while vigorous stirring, then (4) add C (pH=6.9) after following this emulsifying closely, then (5) are cooled to 60 DEG C, then D is added, then (6) are cooled to room temperature, then add the composition of phase E, then (7) add powder (phase F) (except tester) while gentle agitation.
Table 3
What characterize in table 3 comprises in the oil-in-water emulsion type preparation of 15.5% fatty phase, and this copolyamide provides much more excellent than pure polyamide PA12 powder pliability and powder to remain.
In addition, measured the smoothing effect of compositions N by fringe projection method (m é thode de projection de frange), its principle is as follows: for 20 healthy women objects, measures skin rise and fall at crows-feet place by fringe projection.
Fringe projection technology can confirm the change of the skin pattern of crows-feet.The optical system being exclusively used in tolerance surface undulation is used to carry out this measurement.
This system comprises the sensor being connected to projector and being connected on high resolution CCD photographing unit.Average axis and lateral resolution are about 10 microns.
By calculating standard roughness parameter, carry out the analysis of skin surface pattern.Obtain these parameters from the region being measured as 30 × 40 millimeters (12 square centimeters), represent with millimeter.
The parameter of quantification is the acquisition on a series of profiles vertical with microgroove with the wrinkle of relevant range.
Such as, get parms SPt (the most high-amplitude of fluctuating).For crows-feet, the reduction of SPt means alleviating of main wrinkle.
Preparation N causes SPt parameter to reduce by 4% after this product being applied to crows feet area upper 20 minute, reduces by 6% after 2 hours.
This result is equivalent to from spreading after this product in the of 20 minutes, roughness parameter SPt (fluctuating most high-amplitude) significantly reduces (in whole plane average-4%), and be confirmed and strengthen (in whole plane on average-6%) for 2 hours after spreading.This significant change means that the degree of depth of the main wrinkle of crows-feet reduces.
compositions O to P in table 4 and tester 4 are the oil-in-water emulsion type compositionss comprising 26.5% fatty phase.These compositionss are equivalent to the sunscreen cream preparation such as with high SPF (sun protection factor).
For this kind of preparation, in the sensory study being particularly useful for the sun-screening agent with high SPF (sun protection factor), add another specification: the white produced by sunscreen namely observed after spreading remains.When not staying white residual after spreading said preparation on skin, this specification is cited as 0; Stay on skin after spreading a large amount of white residual time, it is cited as 8.
The method preparing following compositions is that (1) merges and heating aqueous phase A to 70 DEG C, (2) merging and heating fat phase B to 70 DEG C, (3) fatty phase B is slowly added in phase A to form emulsion while vigorous stirring, then (4) are cooled to room temperature, then the composition of phase C, then (5) under agitation add phase D, and then (6) add powder (phase E) (except tester) while gentle agitation.
